I know it has 10 bolts on it and I've heard nightmare stories on having a 10 bolt so I'm not looking forward to doing a 14 bolt swap from a 1 ton
What size (diameter) tires will you be running?
What do want your RPM to be when you go through the lights? In what transmission gear (3rd?) and expected speed?
Pick a rear gear that helps you get that RPM.
Others will have valid comments, I’m sure.
